Use opt -S instead of piping bitcode output through llvm-dis. llvm-svn: 81257 2009-09-09 00:34:10 +02:00			`; RUN: opt %s -instcombine -S \| grep {ret i1 false}`
Fix PR2697 by rewriting the '(X / pos) op neg' logic. This also changes a couple other cases for clarity, but shouldn't affect correctness. Patch by Eli Friedman! llvm-svn: 57387 2008-10-12 00:55:00 +02:00			`; PR2697`
